Health monitoring system
First Claim
1. A personal health monitor comprising:
- a portable, physiological monitoring device which periodically and automatically measures and records from a subject physiological data comprising electro-cardiogram (EKG) data descriptive of an EKG signal;
a time base which tracks the time of recording of the physiological data; and
a data storage unit in which the physiological data is stored with reference to the time base, the EKG data including data representative of temporal intervals between occurrences of relevant features of a repeating EKG waveform for each heartbeat, the stored data including interval differences indicative of a difference between the duration of one of said intervals and the duration of a later of said intervals.

Abstract
A health monitoring system which tracks the state of health of a patient and compiles a chronological health history of the patient uses a multiparametric monitor which periodically and automatically measures and records a plurality of physiological data from sensors in contact with the patient'"'"'s body. The data collected is not specifically related to a particular medical condition but, instead, provides the information necessary to derive patterns which are characteristic of healthy patients as well as those who are ill. The data collected is periodically uploaded to a database in which it is stored along with similar health histories for other patients. The monitor is preferably self-contained in a chest strap which is located on the patient'"'"'s torso, and makes use of a controller which controls sampling of the desired data and storage of the data to a local memory device pending uploading to the database. The more voluminous data collected is reduced and compressed prior to storage in the local memory device. Preferably, much of the monitor circuitry is run intermittently to conserve power. The monitor data is supplemented with subjective data (such as psychological and environmental conditions) collected from the patient using a handheld data input device which runs a program to solicit information from the patient. The subjective data collected is chronologically aligned with the monitor data in the database such that the health history of a patient includes both objective and subjective medical data.

13. A personal health monitor comprising:
-
a portable, physiological monitoring device which periodically and automatically measures and records from a subject physiological data comprising electro-cardiogram (EKG) data descriptive of an EKG signal;
a time base which tracks the time of recording of the physiological data; and
a data storage unit in which the physiological data is stored with reference to the time base, wherein the EKG signal comprises an EKG waveform for one heartbeat, and the stored data includes data indicative of a waveform structure of a key segment of the EKG signal, wherein the data indicative of the key segment includes data indicative of a point in time at which a magnitude of the EKG signal crossed a first predetermined threshold and a point in time at which the signal magnitude crossed a second predetermined threshold. - View Dependent Claims (14, 15, 16, 17)
